KENNEDY SPACE CENTER, FLA. - In the Vehicle Assembly Building, United Space Alliance engineer John LaPlante attaches a crane to the External Tank (ET) designated to fly on Return to Flight mission STS-114. The tank is being lifted from a checkout cell prior to mating with the Solid Rocket Boosters. The ET is recently redesigned to meet recommendations of the Columbia Accident Investigation Board before return to flight. Among dozens of changes is a redesigned forward bipod fitting to reduce the risk to the Space Shuttle from falling debris during ascent. Considered a test flight, STS-114 is scheduled to launch during a window extending May 15 to June 3. The Shuttle will carry supplies and equipment to the International Space Station.
